I am going to upgrade my battery cables from 2awg to 2/0. The old cable ran from my battery in the trunk under the car up to the starter. It snaked around suspension parts through and over frame connectors and was tight in places so running the 2/0 in the same path doesn't seem possible. I would rather run the cable through the trunk along the left sill under the carpet and through the firewall to the starter. Is it ok to run the cable through the interior?
